The Bird Site Analyzer 4000 is new to the company’s line. The handheld device is used for checking antennas and feed-line systems for faults and other problems. The unit performs sweeps on the line and antenna systems, checking distance to fault, match, VSWR and other characteristics. A previous model was used primarily in the cellular business and did not go below 806 MHz. The new model reads from 25 MHz to 4000 MHz. Info: www.bird-electronic.com.
